If your starting destination is Bangkok Airport, then it's very easy as there's a door-to-door coach service on the Level One, Gate Number 8 - BELL TRAVEL SERVICE. The ticket price is about

baht. If you are traveling from Bangkok City area, then hire a taxi/hire car from the hotel you're staying at. It should cost around 1200 baht, which includes the tolls (make sure you confirm that in the price). You can catch a bus from Bangkok's Ekamai Bus Terminal (119 baht), on Sukumvit Road. You can get to the Bus Terminal by the BTS Skytrain (Ekamai BTS). I hope this is helpful.
